SELF-ACTING DUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 482,390, datedSeptember 13, 1892.

Application filed May 26, 1892. Serial No. 434,400. (No modelvenient ofaccess.

The objects of our invention are, first, to provide a suitable platformupon which the garbage or material to be dumped may be deposited;second, to suspend the same on a l wire rope secured to derri'cks ormasts, which ropes shall extend from the place where the article is tobe received on the platform and carried out to the place where it isdumped; third, to provide a supporting arrangement for one end of thedumping-platform which will loosen itself when the carriage having thedump-platform reaches the place of dump. We attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure 1is a view of the entire machine. Fig. 2 is a view of the reverse inclineunlockiug one end of the dumping-platform when the carriage reaches thatpoint.

Similar letters refer to similar parts throughout the several views.

A is a dumping-platform, upon which garbage or other material to be domped is placed.

It is suspended uponthe wire P by means of trolley F and wires.

Bis a dumping-hook formed somethinglike a letter T inverted, one shortend of the T being inserted in loop 0, which is hinged to the platform,and the other end is connected by wire G to lever-arms I I, and the stemis suspended from one end of the trolley F.

G is a metal loop hinged to one end of the dumping-platform A, in themiddle thereof, so that when hanging loose it will drop out of the roadof the material to be dumped.

D D are two eye-joints near the other end of the platform, one being oneach side thereof.

E E E are three wires, by which the dumping-platform A is suspended fromtrolley F joints, to which wire cables are attached, supporting platformA.

G is a wire rope connecting lever-arms I I with lock attachment B, thepurpose of this being, when G is elevated, to loosen hook B and allowthe platform to dump.

H is a pulley secured by a pair of leverarms to one end of the trolleyF, supporting wire cable G, and when raised will loosen hook B andpermit the platform to dump itself.

I I is a pair of lever-arms connecting pulley H to one end of trolley F.From the lever-arms I I the wire cable G is suspended.

J J are two pulleys upon the elevated wire cable P and supporting thetrolley F, that carries the platform A.

K is a wire cable fastened to the trolley F, running around a pulley Oand drum M down to Windlass L for the purpose of drawing the trolley Ffrom the place of dump up the inclined wire cable P to where theplatform is to receive material to be dumped.

L is a Windlass worked by a crank having M and O are two cylindersaround which wire cable K is carried.

P is a wire cable mounted at each end on derricks or masts, one end atthe place of receiving the article to be dumped and the other end out inthe river or place where the artiole is to be dumped, the wire cablerunning to the place of dump on a descending inclined plane. The wirecable P is stretched taut and secured rigidly.

Q is a reverse inclined plane, made of metal and cone-shaped, encirclingthe wire cable P and rigidly secured thereto and engaging pulley H asthe platform A and trolley F reach the place of dump.

R R are posts secured near the place of dump, supporting the wire cableP.

S S are two posts or a clerreck mounted at the place of receiving thematerial, supporting the wire cable P.

To operate my machine, the Windlass is turned and the trolley F is drawnup near the derrick S S, carrying with it, supported underneath, theplatform A. This platform is situated where the article to be dumped canbe easily placed thereon. When platform A is loaded sufficientlyfa dog(not shown) is loosened upon the Windlass L, and by its own weight thewhole dumping-platform A and trolley F is carried down the inclinedcable Pto the proper place of dump. Its speed may be checked by almostany device used as a brake at the Windlass L. As the pulley H reachesthe place of dump it strikes the reverse inclined plane Q, and as pulleyH is elevated by that inclined plane it loosens hook B from the loop 0and that end of the platform drops and permits the garbage or othermaterial to leave the platform A and go into the place of dump. It isthen drawn back into place by the Windlass or any suitable power, or theWire K can be placed on a vertical drum near the top of the derrick andbe carried to another similar derrick with a similar dumping apparatus,and the descent of one of the dumping-platforms can be used to carry aduplicate platform when emptied to the place where it is to receive theload, and vice versa.

Having thus fully described our invention, what We claim, and desire tosecure by Letters Patent, is

1. In a dumping apparatus, a platform suspended under an elevatedinclined cable, said platform having eye-joints on each side near oneend and a loop hinged in the middle of the other end, in combinationwith a hook engaging said loop, a trolley on said inclined ca ble tworopes connecting one end of the trolley with the eye-joints on theplatform and secured therein, a rope connecting the other end of thetrolley with the stem of the hook, a pulley on the inclined cableconnected to the trolley by a pair of lever-arms pivoted to saidtrolley, a rope extending from said leverarms to one end of the hook,areverse incline rigidly secured to the inclined cable at place of dump,and suitable power connected by rope to the trolley to return theplatform to its place after dumping, all substantially as described.

2. In a dumping apparatus, the receptacle A, in combination with thelever-lock attachment B, loop 0, eye-joints D D, wire ropes E E E,trolley F, Wire rope G, pulley H, pair of lever-arms I I, Wire rope K,Windlass L, drum M, pulley O, elevated inclined Wire cable P,

reverse incline Q, posts R R, and posts S S,

all substantially as described.
